at /Vaukesha, in the county of Waukesha,"

State of Wisconsin, have invented certain new and useful Improvements in Portable Concrete-Mixers, of which the following is a specification.

My invention relates to the construction of a concrete mixer, whereby many advantages are obtained not possible with concrete mixers heretofore in use; Among the advantages are that the mixer is portable, and owing to its size, shape and construction, may be readily moved from point to point without requiring the exhibition of any considerable effort on the part of the mover. The mixing drum is arranged near to the earth, and is adapted to receive the materials to be mixed atthe rear, and to discharge them from the front end. The motive power which turns .the mixer is mounted over the drum in a position where it will not be subjected to the destructive action of flying dust.

My invention embodies various details of construction ,which will be described in the specification, and specifically pointed out in the claim. 1

The accompanying drawings will serve to illustrate my invention, in which-- Figure 1 is a side elevation of the portable mixer; also showing in dotted lines, the position occupied by the mixer when tilted to move it from place to place. Fig. 2 is a view, partially in elevation, taken on the line lI-II of Fig. 3 and looking from the left. Fig. 3 is a view, partially in elevation, taken substantially on the line IHHI of Fig. 2.

In the drawings, 5 represents a carriage.

frame, which is made up of the longitudinal and transverse channel irons 6-7. At the rear end of the carriage frame is a handle bar 8, and at the forward end, an axle 9 on which are mounted. the wheels 10.

Secured to the channel iron 6 at the rear of the carriage frame, are skidding shoes 11. The forward portion of'the skidding shoes is carried upward to form a brace 12. Lo cated on the forward part of the channel iron 6, is a frame 13, which consists of four vertical members 14 and four horizontally disposed channel irons 15. The frame 13 is substantially rectangular. Located below the channel irons 15, and secured and mounted in bearmgs 16, secured to the channel irons 7, are shafts 17, on which are mounted flange rollers 18. .There are two shafts and four rollers. The tops of the flange rollers 18, it will be seen by reference to the figures,

are located below the top of the channel irons 7. Mounted on the rollers is a mixing dr'um 19, which is preferably made of steel cast in two halves, joined together at the center in any suitable manner. 0n the ex terior of the drum and corresponding in position with the flange rollers 18, are raised trackers 20. Located on the interior of the drum and at the rear of the drum, are a series of concave blades or scoops 21. These blades are inclined downwardly from the back of the drum toward the front of the drum. Located in the front of the drum and alternately disposed as regards the blades, are a series of buckets 22. Arranged in the back of the drum and in the front of the drum are openings 23-24. Secured to the braces 12.by means of an angle iron 25, is an inclined hopper 26, the forward end of which projects into the drum through the opening 23. ,Mounted on an arm 27, pivotally supported on the forward vertical members 1450f the frame 13, is a discharge spout 28, and secured to one of the horizontal members 15 of the frame 13, are hooks 29, adapted to enga e with the upper end of the arm 27 to hold the discharge spout in the position shown in Fig. 1. The two positions which the spout may occupy are respectively shown in Figs. 1 and 2. The braces 12 are connected to the rear vertical members 14 of the frame 13by plates 30 or otherwise, the braces 12 serving to stiffen the frame 13. Located on the top and at the rear of the frame 13, is a motive power device, shown as a gas engine. Manifestly any suitable motive power device may be employed. Situated on the exterior of the drum and over the joint between the two halves of the drum 19, is a segmental tooth driving ring 31. Power is transmitted from the power device to the drum by means of a pinion 32 which meshes with a gear 33 mounted on a shaft 34, carried in bearings 35 on the frame 13, and on the shaft 34, opposite to the position of the gear 33, is a pinion 36 which meshes with the tooth driving ring 31 on the drum.

It will be observed that the motive power device is located at the rear of the frame 13, the object of which arrangement is to provide that when the carriage frame 5 is lifted to the position shown in dotted lines in Fig. 1, the weight of the motive power device shall be located over the driving axle, and thus provide that the operator shall not b9 obliged to support any portion of the weight of the apparatus in moving it from point to point. I

The operation of my im roved mixer will be readily understood. T e material to be mixed is introduced through the hopper 26 (the delivery spout having first been moved to the position shown in Fig. 1) and falls to the bottom of the drum. As the drum is rotated, the concave blades 21 lift the material and throw it toward the front end of the drum and into the buckets 22, from whence it is discharged again into the bottom vof the drum as the drum revolves. After mixing is eflected, the discharge spout is" thrown into the position shown in Fig. 3. Whenin this position the material discharged into the buckets 22 is by them discharged through the spout upon the ground into a wheel-barrow or other receptacle provided for the purpose but not shown.

I wish it understood that I do not limit myself to the specific means described for mounting the drum upon the carriage frame, or for transmitting the power to the .drum, as it will be obvious that these features of construction may be modified without departing from the intent of my invention.

Having thus described my invention, I claim;

In a portable concrete mixer, a suitable running gear, a mixer mounted thereon, a frame carried by said running gear, and a motive power device mounted upon said frame in such a position that the center of gravity of the device will be shifted from its position without the vertical plane of the axle to'a position substantially within said plane when the device is. in position for translation.

In testimony whereof, I .aflix my slgnature,in the presence of two witnesses.
